An optical-interference type display panel and a method for making the same are disclosed, wherein the display panel has a substrate on which multiple first conductive optical film stacks, supporting layers and multiple second conductive optical film stacks are formed. The substrate further has a plurality of connecting pads consisting of a transparent conductive film of the first conductive optical film stacks. Since the transparent conductive film is made of indium tin oxide, these connecting pads have the excellent anti-oxidation ability at their surface.

Optical-interference type display panel and method for making the same

The method for fabricating reflector plate for a reflective liquid crystal display and the device is disclosed. The present invention includes the formation of a protection layer over the glass substrate having thin film transistors and a layer of transparent electrodes on top, followed by the formation of a layer of undulating resin over the protection layer. If the reflector plate to be produced is a semi-transmissive type, a light-transmitting region is created over the protection layer. Since the protection layer is created in advance of the undulating resin outgrowth, the present method can effectively prevent reflection from the exposure stage during the lithography process, thus the problem of abnormal pattern marks occurring on the reflective surface can be avoided, and the exposure time and the production yield are enhanced.

Method for fabricating a semi-transmissive reflector plate

A structure of an ultra-micro reflector having abrasive surface with tapered micro bumps and free of resin layer and its fabrication method are provided. The reflector structure comprises mainly a layer of reflector metal, a scattering element with abrasive surface, and a layer of ITO. The abrasive surface has many tapered micro bumps. The reflector structure can be applied to a reflective or partially reflective LCD to achieve optimal performance. It makes the scattering angle of the reflective light source wider and more uniform. The variation of the gap of liquid crystal cells is greatly reduced, so that the reflective efficiency can be kept in an optimal condition. The reflector structure has larger scattering angle, smooth effect, and very good anti-glare effect. The fabrication process of the reflector structure is simple. The material cost for the abrasive surface is inexpensive. The reflector can endure higher temperature than conventional organic reflective elements, because the inorganic thin film process is used.

Reflector structure in a liquid crystal display and its fabrication method

Method for fabricating a reflective type reflector plate of a reflective liquid crystal display

A reflector structure in a multi-domain liquid crystal display comprises an active matrix device structure having regions of various height levels, a diffusing layer, and a structure of multi-domain reflective layer. The diffusing layer is formed above the active matrix device structure with multiple extruded bumps of various film thickness and various heights and shapes. The reflector structure has various reflective angles and reflective effects to improve the quality of LCD panel. It can be used in the reflective layer of a reflective or semi-reflective TN, STN, TFT, or TFD. The reflector fabrication process uses conventional process for a metal or an insulation layer on a TFT substrate to form multiple domains within a pixel area. After forming the cell structure of the multi-domain reflective layer, liquid crystal cells form multiple domains within a pixel area.
